Hello,   I have 2 CUC and the 2 are installed as Publisher. Can I move one of them from Publisher to subscriber ? Or I must re-install it as subscriber.

Hello All,   I have an Expressway-C, Expressway-E and a CUCM 10.5. I want to add one SX10 and one SX20 endpoints. So what license will be required on The CUCM.   Thanks, Wael
